The behavioral biometric of keystroke dynamics uses the manner and rhythm in which an individual types characters on a keyboard or keypad. [4] [5] [6] The user's keystroke rhythms are measured to develop a unique biometric template of the user's typing pattern for future authentication. [7]
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program.
In cases in which the computer case is hidden from view (e.g. at some public access kiosks where the case is in a locked box and only a monitor, keyboard, and mouse are exposed to view) and the user has no possibility to run software checks, a user might thwart a keylogger by typing part of a password, using the mouse to move to a text editor ...
The origins of keystroke inference attacks can be traced back to the mid-1980s when academic interest first emerged in utilizing various emanations from devices to deduce their state. While keystroke inference attacks were not explicitly discussed during this period, the declassified introductory textbook on TEMPEST standards, NACSIM 5000 ...
[2] [3] [4] Many organizations, including governments, publish and share their datasets. The datasets are classified, based on the licenses, as Open data and Non-Open data. The datasets from various governmental-bodies are presented in List of open government data sites. The datasets are ported on open data portals.
The keyboard sends the key code to the keyboard driver running in the main computer; if the main computer is operating, it commands the light to turn on. All the other indicator lights work in a similar way. The keyboard driver also tracks the shift, alt and control state of the keyboard.
Zeus is very difficult to detect even with up-to-date antivirus and other security software as it hides itself using stealth techniques. [5] It is considered that this is the primary reason why the Zeus malware then had become the largest botnet on the Internet: Damballa estimated that the malware infected 3.6 million PCs in the U.S. in 2009.
